OK, the really obvious ingredient is basil. I'm pretty comfortable identifying truffles as another ingredient. Beneath the fish is what looks like sweet corn, cucumber, and maybe celery.

From there, things get trickier. I have never had a chance to get to know fish really well since I'm not in a fish-rich environment. At a guess, I'm thinking it's something like sea bass -- but tilapia and mahi-mahi are candidates too.

The sauce is another challenge. Since it's more orangey than red, I'm guessing the color is from something like chipotle -- but not in a strong concentration, as that would overpower the other flavors in the dish. I'm not sure what else would be in the sauce, except that you've already given us a strong hint that basil is in there.
